A/N: Thank you for your kind words about my attempt for this crossover. So here is chapter three. Enjoy and don't forget to review.

Disclaimer: I do not own anything in this story, but the idea of the plotline (and not even that is totally mine). Credit goes to Rhimes and Rowling, just so you know. Lucky bitches that they are.

Beta'd by the lovely Challenge King, cheers!


"Sir? The girl's family is asking for an update," one of the surgical nurses spoke as she hung up the phone.

"Seriously? I have a girl on the table with a massive tumor and no organs in her chest cavity. I think that ranks a little higher, don't you?" The Chief spoke irritated.

"Sir, they are very persistent." The nurse spoke. The Chief sighed, highly annoyed. Harry could tell he was not planning on going out there. He hated the stuck up attitude the chief was exuding. From the other side of the table, he could see Bailey and Hahn exchanging glances. They didn't speak though, to Harry's annoyance.

"Chief," he started. "I get you want to be here at the moment, but those parents have already been waiting three hours in fear of their daughter's life. Trust me, you do not want to know what that means." His voice was heady, filled with sadness. The chief looked up.

"What do you mean, Dr. Potter?" He asked him, voice filled with suspicion.

"I mean get the bloody hell out there and sooth their fried nerves, for ruddy sake's!" He snapped. Were all Americans so bloody oblivious for the pain insecurity brought?

Chief Webber shot his new attending a disapproving glare, which he returned full heartedly. With an exasperated sigh, Webber laid down his instruments and walked out of the OR.

"Grey, come standing were the chief was. I need an extra set of hands here." Harry didn't bat an eyelash that he just told off the chief. Looking up he could see the three women looking at him.

"What?" He snapped. The women looked at each other before looking back at him. Bailey was the one to brave the question.

"You seem to speak from experience," she started hesitantly, already prepared for a lashing out. Harry shot the woman a quick look, before continuing clamping of arteries connected to the tumor.

"That's because I am." He retorted curtly. Silence reigned the OR. To his growing annoyance, the women's hand stilled in their work. He forced himself not to curse or yell at them.

"It has been a long time since then. So how about eyes on the clock and doing our ruddy job?" Pointedly nodding at their stilled hands. This shook the women out of their reverie.

Ten minutes later, Chief Webber walked back in the room. "How far along are we?" He asked the operating surgeons.

"We are just about to clamp and cut down the last veins and arteries connected to the tumor," Harry explained him. "Grey, the one next to your left finger. Do you see it?"

"Yes," Meredith responded to him.

"I want you to start preparations for diverting it to the blue labeled veins." Hahn looked up surprised.

"Why would you do such a thing?" she asked.

"To save as much of her own vascular system as possible. Blood flow keeps them stronger, healthier. And the rest is already very frail." Hahn nodded in accordance, it made sense. Her respect for the attending grew.

"You really know your stuff, don't you Dr. Potter?" she asked, continuing to repair the arteries under her hand.

"I should hope so. If not, I suspect the chief here would have a very unhappy resident on his ass." He replied in good humor. Hahn and Bailey were women he could truly appreciate, giving their all to save patients. Not just doing the job for money or prestige.

"I've heard about your little run in down in the pit earlier." Bailey spoke up. Harry snorted.

"You mean with Dr. Shepherd? Heard about this already?" He shook his head in mock despair. "It seems the rumor and gossip mill is even faster than it was in my old boarding school."

Bailey chuckled appreciatively. "Yes, the nurses are very reliable. Just like the residents." She informed him.

"Good to know. So it would be a bad idea to tell Dr. Grey I've been keeping corpses in my locker then?" He replied, giving a wink to Meredith. She looked back, deciding to go with the joke.

"Don't worry. Corpses are not that interesting. Now, say that you kept an illegal supply of animal heart valves, that would be something worth gossiping about."

Harry laughed out loud at that. "I keep that in mind, Grey. Thanks for explaining it to me."

"Crap," Hahn muttered. Harry looked up.

"What is it?" He questioned her.

"There is too much damage here around the lower aorta. The vascular wall is almost completely torn apart." Bailey looked shocked.

"Are there other ways to fix it?" She asked. Hahn looked up and glared.

"No! I told you I don't wanted to do this surgery. That the damage would be too big. But you didn't listen, wanting to do an impossible surgery, to get Seattle Grace back on the number one position on the list!" She burst out, angrily. Before Bailey could retaliate Harry stepped in.

"How about we start talking controversial solutions? Negative attitudes have no business in surgery, Dr. Hahn. So you either shut up, or leave the OR!" He snapped. Hahn recoiled, but nodded. Freaking out and pointing blame could wait until after the surgery. She and Bailey started to talk solutions, until umbilical cords were offered by a hesitant Meredith. Hahn and Bailey looked up.

"That could work. It's life tissue, from the recipient itself." Hahn nodded. "Let's do it."

"Impressive, Grey," Harry complimented the resident. She nodded at his praise.

It was an hour later that the surgeons watched as the gurney with Tori on it was rolled out of the OR towards Recovery.

"Do you think she'll make it?" Bailey asked Harry. He flipped of his face mask, bringing a hand over his face.

"That is up to her, and fate. But we have given her the fighting chance, that's all we could give her." With a comforting squeeze he walked out of the OR. At the door he turned back and looked at the three women.

"Very impressive work, I must say. I can see enjoying myself working with you all." And with a polite nod, he was gone.

"That man is a mystery if I ever saw one," Hahn noted. Bailey looked at her.

"That man is one of the finest surgeons Britain has produced. Look over the medical articles produced about experimental procedures. His name crops up many times." She pointed out to the tall blonde. "That man has been in the field in Iraq and has saved many lives with experimental surgeries and improvising. He's a genius."

"I meant him personally, Bailey." Hahn looked at the smaller woman condescendingly.

"You're a fool," Bailey snarked. Hahn recoiled.

"Are you deaf! The man said he spoke from personal experience. He has lines around his eyes way too deep for a man his age. He knows death." And without sparing the other another glance she walked out of the OR.


Break time found the group of Bailey's residents, minus Christina who was pig-sitting, sitting around drinking absurdly strong coffees. Karev turned to Meredith as soon as she sat with them.

"SO! How was miracle surgery with Potter?" he asked her.

"Amazing. That guy is a genius with a scalpel. But the most amazing thing is he rules the room and surgery. I witnessed him telling off the chief!" She immediately started to gossip. George and Izzie looked up with wide eyes.

"He stopped Bailey and Hahn from bickering, and even on a surgery as this he taught me all about recognizing different tears in both organs and their main vascular systems." Meredith kept on singing his praise. "He is an ass though," she added.

"Who cares about that if he is that good?" Izzie cried out. Karev nodded reluctantly.

"Yeah, I had that spleen earlier with him. The guy totally told off Shepherd as well." He began. "We were just about to bring him to the OR, when Shepherd came and started to spout off how the guy needed a neuro exam." Karev chuckled as he remembered. "So he literally snarled at him: 'This guy is bleeding from a ruptured spleen faster than we can get blood in, and you want to do a neuro?' And then asked if he did he would be responsible for the guy's death." Karev did a very poor British accent as he tried to copy Potter.

"And he has a kid, or had a kid." Meredith said, a bit perturbed that the new guy told Derek off. Though, admittedly he had sort of deserved it if he acted like that.

George cocked his head a bit as Meredith said this. "How do you know this?"

Meredith leaned forward and the other residents copied her. "Well, the girl's family was bugging for an update, the chief got annoyed and didn't want to out there. That's when Potter told him off, said that the parents were going through hell with their only daughter lying on the table. So the chief went out." Meredith took a sip of well-deserved coffee. "Then Bailey said that it looked like he was speaking from experience. That's when he replied that he was."

All the residents leaned back at that tidbit. Izzie stood up.

"Well if he did have or has a kid, who are we to say something about that?" she said.

"Thank you for you staunch support, Dr. Stevens." A British voice sounded from behind Karev and Meredith. Everyone jumped and turned towards the voice. Standing there, was an unamused Dr. Potter.

"Dr. Grey, I thought I made it clear earlier when I paged you. You are the one to stay on Tori's floor. Going to get a coffee is one thing, wasting time gossiping with your colleagues is another." Meredith stood up, draining her coffee as she did.

"The rest of you… Don't you have better things to do than analyze my personality and personal life?" His voice was eerily calm, but his eyebrow was raised threatening. "I teach here, I operate here. That is all you need to know."

With those words he disappeared. Meredith stood there, feeling embarrassed.

"Dr. Grey!" She heard him snap from the doorway. "Those words were not a kind suggestion! That was an order to get your arse in gear and monitor Tori!"

Meredith snapped out of her shock, and ran after him.

"Holy…" George stammered. Alex nodded fervently in agreement. Yup, dr. Potter was scary as hell, when he wanted to be.


Christina was working feverishly to keep her pigs alive. She looked in disbelief as she saw Lexipedia petting the snout of one of the pigs, and heard her speak to it comfortingly. She drew the line when she heard the interns give them names, though.

"NO! no nicknames, no lovey-dovey, no!" She berated the interns. "I do not want you to form some idiotic emotional attachment to these piles of bacon. We just need to keep them alive, and healthy. That's it! It's not like porky and bacon are going to complain about or bedside manners."

With that she turned back on the pig she was currently stitching up. The doors opened and she could she one of Alex's interns walking in. What was his name again, right! Pierce! What the hell was Pierce doing in the piggy bank? She knew about the crash that had happened, and all the other residents had left for the pit with her interns.

"I have just scrubbed in with Dr. Karev and the new attending." He told her minions smugly. "AND, Dr. Potter has taught me how to search for internal bleeding with ultrasound. He's pretty great, we were allowed to hold clamps and suction and all during surgery."

Yang rolled her eyes. Seriously, the guy got smug for holding a clamp? Lexie Grey turned to Pierce and demanded more information.

"Well… the guy came in to the pit and demanded one trauma from dr. Hunt, you know the new head of trauma, and Hunt just threw a chart at him. Turned out it was Dr. Karev's case. He walked in, immediately going for the vital stats. Then suddenly, bam, guy began to crash. He just put pressure on some points in the abdomen and demanded the ultrasound. He then explained how best to search for bleeders."

Lexie was looking wide-eyed with awe at this story.

"Lexipedia, no need to get jealous. You've just performed several highly invasive procedures, with only resident's assistance. Even if it was on a pig." Christina sneered. Lexie nodded, putting her chin up to Pierce,

"And you, Alex's Two, why are you here? Don't you have a nice room full of sutures?" Christina looked pointedly at him. Pierce disappeared very fast from the room.


Harry was working on some of his surgical notes in the chart of spleen guy at the desk by the OR board. To his immense displeasure, he was interrupted by the pretty boy brigade. They are like teenage girls, he thought to himself, continuously traveling in packs.

"Potter," Sloan spoke. Harry turned to them, keeping his facial expressions passive.

"We just want to inquire how your surgeries went this day. First day and all, we want to welcome you to our team." He brought out a winning smile at the end. Harry kept looking from him to Shepherd.

"They both went well, thank you. Both patients look like they survive their ordeal on my table." He replied, relying heavily on his house politics lessons with Andromeda. After the war, she had dragged him by the ear and forced all proper manners and political games in his head. He never felt more Slytherin as he had after she completed their lessons.

"That is always good news," Derek Shepherd continued were his friend left of. They reminded him starkly of the bond the Weasley siblings had.

"Can I ask you two a personal question?" He blurted out before he could put a check on it. The two looked surprised but nodded their agreement nonetheless.

"Are you two related, grew up together or something alike?" Their surprise turned into shock. Sloan was the first to recover from his shock.

"We did grow up together. Both from New York, Derek has been my friend since infancy." They gave each other a half-smile. Harry nodded.

"You can tell," was all he said. Derek turned to Harry.

"I wanted to apologize for earlier." Harry lifted his eyebrow. "It was just that Hunt forced us out of the pit, and we saw all those trauma's around us…" Derek trailed off.

"You are head of Neuro and Plastics, and you were cruising the pit for pick-me-ups?" Harry could help but chuckle. "There was one case Hunt suspected to be surgical, general surgery to be precise. That is the reason I was paged. One thing you do need to know is that when an attending is on his way to the OR, you do not stop him with asinine questions. If I had needed a neuro consult, I would have had the nurses page you. You made me seem incompetent in front of residents and interns. That is something I will not allow."

Derek nodded his head, he understood where the guy was coming from. Harry wasn't finished though.

"Furthermore I cannot help but be shocked at the capability of some of the interns and residents. I do not know how you all teach in this hospital, but one starts to wonder when a second year surgical intern does not know how to properly do an ultrasounds for internal bleeding."

They both frowned at that. They hadn't known that, and it was indeed worrying.

"I'll talk to the chief about it." Derek promised. Harry nodded and held out his hand.

"Well then, gentleman. How about a restart? Nice to meet you, the name is Harry Potter and I just started my new job as senior attending for general surgery at Seattle Grace."

Sloan smiled and shook his hand, with Derek following him.

"By the way, have you heard what Dr. Hunt had prepared for the residents to test their trauma surgical capabilities?" Mark asked as they walked slowly to the post-operations floor. Harry snorted.

"Heard? He stood on my threshold this morning, pleading me to help him get the pigs inside the hospital." Mark and Derek turned to look at him in, once again, shock. Harry nodded, still chuckling.

"Yes, crazy-arsed man he is. Still, it is true. I suspect he stabbed them all? Dr. Stevens was ranting to me at lunch. Funny how a resident who hasn't spoken a word to me still looks at me, like I am the one to solve that particular problem."

Mark and Derek both laughed at that. They both had experience with the hair-brained frazzity that was Izzie Stevens.

"Hey, want to go for drinks after our shift is over?" Mark asked the Brit before he could walk away. He turned around.

"Sure, meet you in the lobby downstairs at six?" Harry asked. They both nodded and with a last wave over the shoulder, they parted.

Harry made his way to Tori's room. He really wanted to keep a close eye on her, and was planning on calling up some interns that would get to play night watch with her. Her parents were sitting next to her bed, just like Harry suspected. Walking in with the chart, he started to check her vitals and medication.

"Do you, do you think she'll wake up?" Mrs. Begler was in tears. Harry put a hand on her shoulder and smiled warmly at her.

"Not tonight, madam. A normal surgery removing a tumor is already extensive and evasive on the human body. But her organs had a rough time as well, and that sort of stress on the body need time to get processed. She'll be asleep at least until tomorrow morning, but I estimate it to continue through the day and maybe into the evening. So even if she doesn't wake by morning, do not let that scare you." Her mother nodded, as she firmly grasped her husband's hand.

"Her vitals are good, and her kidney function is even better than I could have expected. She responds to the medication, and that keeps the stress on her body at the minimum." Harry looked at the parents, and could see that they still had the fear in their eyes. He drew up a chair and sat facing them.

"Mr. and Mrs. Begler, I know this is scary as hell." He began, but got interrupted by Tori's father.

"How the hell do you know! All you doctors say that, but until you have to watch helplessly as your daughter withers away, I cannot believe your sympathies." He growled.

"But I have sat where you sat," Harry spoke softly. This shut the man up and he looked intensely at Harry. "I had, I had a baby boy. He got very ill, and even though I am a doctor I could not help my boy. I save lives on a daily basis, but still I could do nothing but sit and pray." He forced in a lungful of breath.

"But here is what I also know, from professional experience; the stronger the spirit of the patient, the more chance she has to overcome such experiences. And Tori, Tori is a fighter. We managed to get all of the tumor out, and her organs are working even after we had them removed for such an extended period. So this is all good news. But you have to give your girl time, allow her a little bit more rest before she has to get back in the ring. Because what I have seen of her, she'll start swinging immediately." Mrs. Begler sobbed quietly and chuckled watery as Harry spoke of Tori.

"I'll be back early tomorrow morning. I make sure that the night nurse, and some of the doctor's on the night shift will keep a very close eye on her." And with a final squeeze of their hands, Harry stood up. As he was about to leave, Tori's mother asked a dreaded question.

"Your boy, did he- did he make it?" she asked him softly. Harry turned around and smiled sadly.

"No, in the end he was too tired to keep on fighting. So I had to let him go, to give him his well-deserved peace." And he fled the room, and the post-operative floor as fast as he could.

Meredith stood next to the door with her mouth hanging open. The man had lost his child! Meredith had seen parents lose their children here in the hospital. But to hear the wary, accepted grief in his voice was heart-tearing. She decided then and there that no one in the hospital needed to know. She would only tell Derek and make him swear not to breath a word of it to others, especially Mark.

She lifted her hand to find a tear making its way down her face. She haphazardly wiped it away and made her way to a relaxing chair at the nurses desk. She was not about to let Tori out of her sight this night, not after being berated by Potter twice.


Christina and her interns were giving Owen Hunt the update about the pigs when Potter walked in. He smiled amusedly when he figured out that they had nicknamed the pigs. Hilarious, really. After they had finished their presentation, Harry stepped in.

"Dr. Yang, Dr. Hunt, I need two interns, who don't mind some hard work." All the interns looked briefly at each other before all their hands lifted in the air.

"Dr. Yang, this is for post-operative watch on a high-risk patient of mine. In your experience, which of your interns performed best today and is the most adequate in post-op complications?" Christina smiled, knowing exactly what Potter was playing at. All day, they had been slaving over these pigs. Interns hadn't learned a damn thing, now they had a small reward by getting a sleepless night.

"Grey, Watson, congratulations. You just won yourself a shift with Dr. Potter." Christina, Owen and Harry watched as Steve and Lexie jumped up and down a few times.

"Okay, bouncing balls... follow me." The two scrambled after him as he made his way back to the post-op floor. Standing in front of the swing doors, he turned back around.

"First names?" he asked curtly.

"Steve," "Lexie" They answered, way too hyper too Harry's liking.

"Okay, here is the deal. First; tone down the happiness. Behind these doors, there is a ten-year old girl recovering from probably the most extensive and invasive surgery she'll have in her entire life. Her parents are sitting at her bedside, this is their last hope after they have watched their daughter suffer from this for three years. I do not want happiness, giddiness or glee after we walk through these doors. I want sympathy, professionalism and watchfulness. Second, one of you two will need to be on this floor all times, until I come back at five for my pre-rounds check on her. Thirdly; dr. Grey will be the resident of her case this night. Any complications or test results you do not understand or feel iffy about; you page her. I don't care how she reacts. Understood?" He locked them both in his stern green gaze. They swallowed and nodded.

"Understood, Dr. Potter." Harry nodded and beckoned them on.

"Come on, I'll introduce you to the parents." The three of them walked on the floor and made their way to Tori's room.

"Mr. and Mrs. Begler?" Harry asked the parents softly. They looked up at them. Harry smiled slightly and gestured to the two behind them.

"This is Dr. Watson and Dr. Grey. One of them will be around this floor all the time. If you have worries, you ask these two or dr. Meredith Grey about them. They will come in multiple times this night to do some test on Tori, this is routine and nothing to be alarmed about." The parents nodded and greeted the two interns with a small wave.

"I'll see you tomorrow." And with a last piercing glance at the two interns, Harry was off. He quickly walked to the phone and called up Owen, who was still in the clinic he knew.

"Yes?" His gruff voice came over the phone.

"Sloan and Shepherd invited me for drinks. You come as well. Be in the lobby at six." Harry ordered him.

"Now wait a minute," Owen was protesting.

"Owen, you showed up at my door way too early with a lorry full of pigs I helped you unload. You will be having drinks with Mark, Derek and me." Silence was all Harry heard for a minute before…

"Fine, but they better buy me a scotch." Owen grumbled. Harry laughed.

"That's the spirit!"

Six o'clock saw the four surgeons in the lobby looking at each other. Three of them turned to Harry.

"Look, I don't care what happened between the three of you today. I had to play emotional baby-sitter to not only patients' family, but to interns residents and even bloody attendings as well. So you two," he pointed at Derek and Mark, "better show me the way to a bar where I can drink a good single malt, pronto."

"Alright then, shall we?" Derek walked out of the hospital, clearly showing them the way. Owen shrugged with a small chuckle.

"Still got it, eh Harry?" Owen made fun of Harry. Mark looked at Owen for more explanation.

"Harry could make any guy in the force feel like they were being berated by their mother, instead of a general surgeon." Owen elaborated. Harry walked after Derek with a dismissive gesture to Owen.

"It's a gift, Owen. But I only use it for good."

Mark and Owen laughed at that and followed Derek and Harry to Joe's. They all needed a scotch after this day.

Mark turned to Owen, "So what is this, that I keep hearing stuff about pigs all day?"
